Shape-controlled synthesis of phosphor K2SiF6:Mn4+nanorods and their luminescence properties

A red phosphor K₂SiF₆:Mn⁴⁺nanorod is successfully prepared through an efficient one-step method at room temperature for 30 min. Under UV excitation, K₂SiF₆:Mn⁴⁺nanorods show better red emission corresponding to the characteristic lines of Mn⁴⁺compared to bulk materials.
